1965 Map of Rock Spring Table

About this map

Summit Lake Indian Reservation anchors this high-desert terrain, where the waters of Summit Lake sit framed by the Big Rock Mountain Range and Mahogany Mountain. The landscape is a network of survival and early settlement, marked by established cattle outposts like Wilson Ranch and Alkali Ranch. The map reveals the historical military footprint of the region, specifically at Camp McGarry (Ruins) and the sprawling Old Military Reservation Bdy, which speak to a nineteenth-century frontier presence. In this arid basin, water is the primary organizer of human activity, as evidenced by the numerous named water sources such as Chokecherry Spring, Tenmile Spring, and the Alkali Reservoir. The northern reaches are defined by the broad plateau of Rock Spring Table, while the south includes local landmarks like Bear Buttes and the Summit Lake Cem.
